If clearing the cookies doesn't help then it is possible that the file <i>cookies.sqlite</i> that stores the cookies is corrupted.
Rename (or delete) <b>cookies.sqlite</b (cookies.sqlite.old) and delete <b>cookies.sqlite-journal</b> and <b>cookies.txt</b>, if they exist, in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] in case cookies.sqlite got corrupted.

Using Vista Home Premium
Unfortunately this doesn't work on some web sites. When choosing the snipping tool the screen just goes black. Checking or un-checking any of the boxes in 'options' makes no difference. Once this happens you can't even snip from a screen in Word, Excel etc until you shut down Mozilla when the snipping tool starts working again. I am guessing its something to do with the security settings in Mozilla but I don't know.
Can anyone help?

It is possible that the snipping tools doesn't work properly on pages that embed plugins via the plugin-container process.
You can look at these extensions to take a screenshot of web pages:
*Abduction!: https://addons.mozilla.org/firefox/addon/3408
*FireShot: https://addons.mozilla.org/firefox/addon/5648
*Pixlr Grabber: https://addons.mozilla.org/firefox/addon/9924/
*WIPS: https://addons.mozilla.org/firefox/addon/146364/
*Screengrab: https://addons.mozilla.org/firefox/addon/1146

I'm on a pc laptop Win7, screen shot works with my external keyboard, not the laptop keyboard. I know it's probably the laptop itself but there are other oddities w/Firfox between the 2 also. Is there a keystroke (besides alt+prt scrn) that might work?
thanks!

Ctrl + PRTSC only copies the current window to the clipboard.
Extensions allow you to make a screenshot of the entire page including what is hidden and would require scrolling to get into display.
